It seems that every time we use the black tank flush water comes out from the under belly where the tank drain valve comes out of. Since the underbelly is covered I can’t tell where the water is coming from. The leaking water seems to be fresh water and not leaking from the black tank water line. Could there be a problem with the fresh water line going into the black water flush line? My son thinks that water some how leaks and the underbelly plastic catches and then slowly drips out. Anyone else experienced this problem? TIA.
Yup, I'd agree on the water type and your son.
Prolly a loose connection at the fitting or the tank sprayer(s).
Only one way to find out, cut an inspection flap. If you have my luck, it'll two or three flaps. Lol!
Good luck!

I think you will find a check valve in the flush line that goes to the black tank is bad. They are known to leak when flushing. Here is a pic of one in my Precept. They have to be higher than the tank so it’s probably in a cabinet somewhere.Not sure if check valve is the right word. It’s like a vacuum breaker valve.
